Lets see.....where to begin.....
I thought I would build my own LR 308 from parts as the money came in. In the meantime I could have bought probably a seven or eight LR 308's. Anyway, I got all my parts together and took them down to have a guy put it all together for me. The parts (DPMS lower, upper, lpk, carbine stock, 16" AP4 barrel) JP handguard and extension, essentially all DPMS with the exception of the handguard and BC comp. (DPMS barrel from Midway USA, I left a review of the truth and we will see over the next week if they post it)
The 1st problem I had was the threads on the JP barrel nut not matching the threads on the upper receiver. This only took about a month of sending parts back and forth to JP to get this resolved (a much longer drama summarized). Then once the whole thing is finally assembled I take it out to the range and.......the barrel wasn't head spaced. Off to the local gunsmith. Once there he had to ream the chamber for factory 150 grain .308 to fit. Also, the extractor was so stiff he had to replace the factory springs for the extractor to move. That was all done and finally back to the range!
Oh yea, had the wife pick up the rear sight/carry handle and she came home with the wrong one (Armalite) not the one for the DPMS. So, there is a little difference between the two as the Armalite sits higher. So, I thought I would see if I could make it work, and I wasn't able to. So, I went ahead and burned through 50 of my handloads to check for functioning, etc. I had one double feed! (the only good news to this point).
Now, I have the DPMS carry handle (Armalite one for sale $100 shipped if anyone is interested) and haven't had time to go back to the range. I am just itching to sight this thing in and see what kind of group I come up with.
After all that, next time, I think I will buy a stripped down factory model and just change the few parts that I want. But, hey it was fun (not) live and learn.
